# NumberRangeType

> A kind of number the system issues, for example sales invoice numbers. A client must not assume it knows all keys.



**Kind**: `object`

## Fields

**`key`**: `String!`

The stable key of the type, upper case words joined by underscores (UPPER_SNAKE_CASE), for example 'SALES_INVOICE'. It is the value of 'typeKey' on number ranges. Responses always carry the key in upper case; filter values and arguments are accepted in any case. The set of keys can grow: a key that a client does not know is not an error.

---

**`name`**: `String!`

The name of the type in the language of the caller.

---

**`description`**: `String`

A short explanation in the language of the caller; not every type has one.
